No go.... Damnit!
Start her up, Choke's bringing RPMs up as it should, Down to idle and it slowly dies. I get out and look at the carb and it's still trickling gas from the round thingy... I'll get a pic and illustrate... Also the maintainance guy stopped by and said it may be related to the vacuum advance??? He crazy? or could this be the case?
